Scala Stack pushAll() method with example

In Scala Stack class, the pushAll() method is utilized to add the elements from a collection to a stack.

Method Definition: def pushAll(elems: IterableOnce[A]): Stack.this.type

Return Type: It returns a stack that contains all the elements of the given collection.

Example #1:

// Scala program of pushAll()
// method

import scala.collection.mutable.Stack

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a stack
        var s1 = Stack[String]()

        // Creating a set
        var s2 = Set("C++", "Java", "Python", "Scala")

        // Print the set
        println(s2)

        // Applying pushAll method
        s1.pushAll(s2)

        // Print the stack
        println(s1)

    }
}

Output:

Set(C++, Java, Python, Scala)
Stack(Scala, Python, Java, C++)

Example #2:

// Scala program of pushAll()
// method

import scala.collection.mutable.Stack

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a stack
        var s1 = Stack[String]()

        // Creating another stack
        var s2 = Stack("C++", "Java", "Python", "Scala")

        // Print the stack
        println(s2)

        // Applying pushAll method
        s1.pushAll(s2)

        // Print the stack
        println(s1)

    }
}

Output:

Stack(C++, Java, Python, Scala)
Stack(Scala, Python, Java, C++)
